Application filed November 24, 1909, Serial No. 529,750. Renewed November 13, 1911. Seria1 No. 680,190.

To all whom, it may concern:

7 Be it known that I, ISAAC S. DEMnN'r, a citizen of the United States, and a resident of St. Nicholas, in the county of Duval and State of Florida, have invented certain new andv useful Improvements in CountinglVheels, of which the following, when taken in connection with the drawing accompanying and forming a part hereof, is a full and complete description, sufficient to enable those skilled in the art to which it pertains to understand, make, and use the same.

This invention relates to printing wheels used in registerin dating, numbering, adding' and other li e machines, where a resetting of said wheels is desired.

One of the objects of the invention is to obtain a3 printing wheel by means of which a character printed therefrom will be of the color of the material on which it is printed; and a; wheel ,which can be used also for observation of the characters thereon, or, by reversing the bends on one of the'members thereof a printing of the color of the ink will be obtained; while at the same time said wheels and the shaft on which they are mounted are so connected that a plurality of said wheels on said shaft can be re-set at any one of said characters, (say zero), by a single complete turn of said shaft. And a further ob ect of the invention is to obtain a wheel and shaft of the kind named which is economically made, easy to operate, and durable.

In the drawing referred to I have illustrated a device embodying. the invention provided with numerals from one to zero on its periphery, said numerals being raised out from said periphery; and I have also illustrated a' manner of making the device whereby the numerals, from one to. zero, will be pressed into said periphery.

. Fi e 1 is aplan View of a blank provide with radial projections having figures thereon. Fig. 2 is an edge elevation of the blank illustrated in Fig. 1. Fig. 3 is an' elevation of the blank illustrated in Figs; 1 and? 2 with the radial projections thereof turned-to the right, .when said blank is viewedas shown in Fig. 2, so that raised characters are obtained on the eriphery of edge elevation of the blank illustrated in Figs. 1 and 4, with the radial projections of said blank turned to the left, to obtain depressed characters on the periphery of the wheel of which said blank 1s a member. Fig. 6 is a front elevation of a blank disk, provided with a recess, forming an element in" the device-embodying the invention. Fig.-7 is" a vertical sectional view of a wheel embod ing the invention, including a section of t e shaft constitutin a member of the device. Fig. 8 is a vertical sectional View of the device viewed at an angle of ninety degrees to the view in Fig. 7. Fig. 9 is a perspective of a pawl of the kind used to actuate a plurality of the wheels of the device.

.A reference letter applied to designate a given part is used to indicate such part throughout the several figures of the drawing, wherever the same appears? A is a blank provided with the central aperture a, with the additional aperture a, and with the peripherallugs or cars B'.

X are numerals forced out of (or into), the body of the lugs or ears B. The numerals X, (which in the drawing commence with zero and end with nine), when viewed from one side of blank A appear raised and when viewed from the other side of said blank appear depressed.

C, C, are broken lines on which the several lugs or ears B are bent, (to the right or to the left as required), to lay atsubstantially right angles to the remainder of the blank A, in the completed device". When the several ears B are bent to the right, as illustrated in Fig. 4, the numerals X appear as raised characters, and when said ears are bent to the left, as in Fig. 5, these'numerals appear as depressed characters. When the wheel member of the device is" to be used as a printing wheel I bend these lugs or cars to the right as in Fig. 4 and when said whebls are "to be observedthrough a slot or other aperture I turn them to-the left, asin Fig. 6, is a blank from which one mentber of the wheels of the device is obtained. 03 is a central aperture in blank D. d is an additional aperture in said blank, and D" a cylindrical body. -Said cylindrical body is provided with a hole or aperture therethrough' by means of recess E. Cylindrical body D is made of suitable diameter to fit closely to the several ears B, after such ears have been formed at right angles to the main body part of blank A and-the members obtained from said blanks A and D are joinedtogether. The apertures a in blank A, and d in blank D are equally distant fro-m the center of the blanks A and D and are so arranged relative to ears or lugs B and reoess E, that when said apertures ad are opposite each other the recess E will come blanks A and D.

1 h is the engaging end of the pawl or dog H and 7:. is the opposite end of said pawl. End 71. of pawl H comes in contact with the inner face of the cylindrical body D to limit the outward movement of end h.

I is a spring contained in the wheel and arranged so that theend 2' thereof engages t with the pawl H toyieldingly hold the engaging end it of said dog in an advanced position. When the spring I is made of wire as illustrated in the'drawing the pawl H is provided with recess 2" in which recess the ends 71 of said spring are retained to maintain said spring in an operative position.

In assembling the several parts forming the wheel pawl H is placed on pin G, one of the en s g, g, of said pin G is placed in aperture 03 of the member obtained from blank D, the spring I is placed in said member with end 1; in recess 2" and the member obtained from blank A is then joined to said assembled 'members, with the remaining end 9 of pin G in aperture a. Ends 9 extend through the apertures a, d, so as to be riveted over to hold both members of the wheel firmly in place, and after the several parts are assembled as above set forth said ends are riveted.

J is a shaft forming an element of the device and is provided with;a single ratchet tooth y. This ratchet tooth 9' consists of a properly shaped groove of suitable length cut in shaft J. Any desired number of said wheels are loosely mounted on shaft J.

K is a spring arranged to engage with the periphery of the wheel of the device.

The comb F is designed to be suitably mounted and moved reciprocally with the several fingers f, f, f, f, thereof in contact with the periphery of one or more of the wheels of the device. The finger f will at each alternate cycle of the movement of the said edge of a lug on the adjacent wheel, of

next higher denomination, and said adj acent wheel will also be moved one step. The

several recesses E are arranged relative to the numerals on the wheels so that the adjacent wheel of next higher denomination is moved by said comb F when the printing or exposed figure 9 of the wheel of lower denomination is moved and zero substituted in its place.

The operation is the same with all the wheels actuated by a given comb, and the number of said wheels mounted on the shaft J corresponds with the number of fingers on the'comb, whichmay be more or less than is shown in Fig. 9.

When a given count has been obtained from the wheels mounted on shaft J and the wheels are to be re-set at zero, said shaft is turned once around. In turning the shaft J once around, if any of the wheels mounted thereon have not been moved from their initial position said wheel or wheels will be turned once around with said shaft and the zero on said wheel will again be presented to sight or for printing, so that the effect is the same as if said wheel or wheels had not been moved. Those of said wheels which have been moved by comb F will be held stationary by spring K until the pawls H therein are engaged by the turning of ratchet tooth y' of shaft K. After the engagement of said ratchet tooth j with pawl H the wheel in which said pawl is mounted will'be forced around with the shaft, and when said shaft completes its revolution the zero on said wheel will be exposed to sight or for printing. A single turn of the'shaft J therefore re -sets all the wheels mounted thereon which contain a pawl H.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is;

1. The combination, of a member provided with a plurality of lugs arranged in planes concentric to the axis of said member with an additional member provided with a flange fitting said lugs, said members having central openings concentric to said lugs and flange, a pawl mounted between the members, a shaft fitting loosely in said central openings, a ratchet tooth on said shaft, means yieldingly to hold the pawl in position for engagement with said ratchet tooth, and one of said members having numerals on the periphery thereof.

2. A wheel comprisingmetallic members, one having lugs in planes at right angles to the remaining portion of said memberand the other having a cylindrical portion fiting the lugs of the first named member, each of said members having a central aperture, a shaft loosely fitting said apertures, a ratchet tooth forsaid shaft, a pivotally mounted pawl between the members, means arranged to force the pawl toward said ratchet tooth, and numerals on one of said members.

5. A Wheel comprising a plurality of members, one having lugs arranged in planes at right angles to the remaining portion of said member and the other having a cylindrical portion fitting said lugs, each of said members having a central aperture and an additional aperture, a shaft loosely fit- 15 pin between said members, a spring for forc- 20 ing said pawl toward said ratchet tooth, and numerals on one of said members.
